Title: Visual encryption method for grayscale image
Inventor: YAN BIN
IPC: G06T1/00
Filed: 2018-08-24
Abstract: A visual encryption method for a grayscale image. The method places, into an error diffusion feedback loop, the two processes of generating a shared image and overlaying decoding in a visual password. At an encoder end, each pixel or image block is sequentially processed according to a certain scan sequence. Inspection of an overlaying decoding effect is performed instantly on each pixel or image block of a generated shared image. A reconstructed target image acquired after overlaying and an original secret image are compared to acquire a difference therebetween. The difference is fed back and diffused to a surrounding pixel or image block that is not yet quantified, thereby improving the quality of a decoded and reconstructed secret image. An analysis process corresponds to a process of generating a shared image from a secret image. A synthetic process corresponds to a process of acquiring a target image from a shared image. The method incorporates synthesis in analysis, i.e., adopts synthesis-based analysis.
